<p>With the continuous evolution and widespread application of digital twin technology, the demand for digital twin models is no longer confined to static operational displays, but rather dynamic, harmonized, and adaptable models. This necessitates the decoupling of various modules within digital twin models. It needs the establishment of a comprehensive connection model to facilitate information exchange and data flow between different components. To transition digital twins from static showcases to dynamic coordination, a methodology for constructing digital twin connection model based on virtual sensors has been proposed. This method approach utilizes virtual sensors to perceptively gather the dynamic variations of the remaining four dimensions in a five-dimensional model, feeding back these changes to the relevant models. Consequently, the construction of digital twin connectivity modules is achieved, enabling self-updating, self-adjusting, and self-adapting interactions between the five-dimensional digital twin models. By using the digital twin connection model construction method based on virtual sensors, we established a digital twin model for the cross-linking machine in the cable factory's high-pressure workshop, successfully constructing the connection model. This facilitated dynamic coordination of the external four-dimensional models within the connection model, validating the effectiveness of this approach.</p>
